Is the test of "Area of Two Circles' Intersection" correct?

Revision en1, by yamaton, 2015-12-02 23:24:53

600D - Area of Two Circles' Intersection requires hardcore treatment of loss of significance, more than the geometry problem itself.

Let's review the problem, first. We need three numbers (r1, r2, d); where d is the distance between two centers.

Intersection is determined from two circular sectors subtracted by two triangles.
